Wireshark throws an exception when dissecting and RPC v2 packet.  The error
shown in the Packet Decode is:

[Dissector bug, protocol RPC: C:\Development\Wireshark\epan\reassemble.c:1223:
failed assertion "tvb_bytes_exist(tvb, offset, frag_data_len)"]

I am running a debug build of Wireshark, although I get the same problem with
the MSI download package for Wireshark v.2.0.

See frame 20 of the attached pcap file.  I've also attached a stackdump taken
at the time of the problem.
